2-Phenoxy-1,3,2-diazaphospha-[3]ferrocenophane and related derivatives (oxide, sulfide, selenide) were prepared, characterized in solution by multinuclear magnetic resonance methods (1D and 2D 1H, 13C, 15N and 31P NMR) and in the solid state by X-ray structural analysis. The conformation of the 2-phenoxy derivative differs from that of the 2-tert-butyl compound. For further comparison, 2-R2,3-d...

The previously synthesized strained distannadiyl-ansa half-sandwich complex [{κ-SntBu2SntBu2-(η-C5H5)}Ru(CO)2] was investigated with respect to its reactivity toward group 16 elements and bis(tert-butylisonitrile)palladium(0). All products were analyzed by multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis. [{κ-SntBu2SSntBu2-(η-C5H5)}Ru(CO)2] was furthermore characterized by ...

Homoleptic coordination of the neutral diphosphines Me2P(CH2)2PMe2 and o-C6H4(PMe2)2 to the hard Li(+) and Na(+) cations is achieved using Li[Al{OC(CF3)3}4] and Na[B{3,5-(CF3)2-C6H3}4] as 'naked' cation sources. Crystallographic, solid state and solution multinuclear NMR studies confirm distorted octahedral coordination solely via three chelating diphosphines in these unique species.

Covalent amphiphilic polyoxometalates generated from alkylphosphonic acids have been synthesized, characterized and monitored by multinuclear NMR spectroscopy. Among them, K3H[γ-SiW10O36(C12H25PO)2] has been successfully used as a surfactant for the stabilization of a Winsor I type microemulsion system.

cis-[(Cy3P)2Pt{B(OMe)2}2] (1) was obtained in quantitative yield and fully characterised. The thermal stability of 1 was investigated in solution using multinuclear NMR spectroscopy revealing a hitherto unknown temperature-dependent equilibrium between 1 and the corresponding starting materials [Pt(PCy3)2] and free B2(OMe)4.

Free radical polymerization of B-vinyl- and B-styryl-functionalized azaborinine monomers gives well-defined hybrid polymers that were fully characterized by multinuclear NMR and GPC analysis; their solubility, thermal characteristics, and photophysical properties are dramatically different from those of the all-carbon polystyrene analogues.

A platinum Chugaev complex was synthesised and fully characterized by multinuclear NMR spectroscopy and X-ray crystallography. This cis bis acyclic diamino carbene complex acts as a cytotoxic compound and behaves as a cisplatin equivalent by interacting with supercoiled DNA and thiols. Stability of the ligand is also discussed.

The UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase LpxC catalyzes the committed reaction of lipid A biosynthesis, an essential pathway in Gram-negative bacteria. We report the backbone resonance assignments of the 34 kDa LpxC from Escherichia coli in complex with the antibiotic L-161,240 using multidimensional, multinuclear NMR experiments. The H chemical shifts of complexed L-1...
